IMPROVEMENT IN Pl PE-TONGS.

Specification forming part of Letters Patent No. 202,089, dated April 9,1878 application filed January 2, 1878.

To all whom it may concern:

Be it known that I, HENRY BADOOOK, of St. Petcrsburg, in the county ofOlarion and State of Pennsylvania, have invented a new and usefulImprovement in Pipe-Tongs and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in pipe-tongs; and consists inthe combination of two jaws and a lever, constructed andpivoted-together in the manner hereinafter described.

To enable others skilled 'in the art to make and use my invention, Iwill proceed to describe its construction and operation. v

In the accompanying drawings, which form part of this specification,Figure 1 is a side view of my improvement. Fig. 2 is an edge View of thesame.

In the drawings, A represents the hookjaw; B, the clamping-jaw, fromwhich projects an arm, 0, which is fitted in a slot in the jaw A. Drepresents the operating-lever, which is pivoted at f in the jaw A, andat g in the jaw B. The arm 0 of the jaw B is connected at e in the jawB. The jaws are opened by moving the lever in the direction indicated bythe arrow 1, and close uponthe pipe by moving the lever D in thedirection indicated by the arrow 2.

The contour of the several parts is clearly shown in the accompanyingdrawings.

The jaws A and B should be made of caststeel, and may be formed by thecasting process, thereby avoiding the cost and labor of forging them.The lever is constructed of wrought-iron.

Pipe-tongs constructed as hereinbefore described will grasp the pipe inproportion to the force applied to the lever D.

Having thus described my improvement, I claim- A pipe-tongs consistingof the jaws A and B, both pivoted to the lever D, and coupled togetherby the arm 0, which is :pivoted to the jaw A, substantially as hereindescribed.
